Connected to Wi-Fi but without internet (Redmi Note 9 Pro)

[myzule]

Hello.
Phone is connected to Wi-Fi, but without internet access. Wi-Fi works perfectly fine on other phones or laptop. Also phone is updated (MIUI 12.0.4).

Here’s what I’ve tried so far:
- Forgetting the Wi-Fi then connecting again
- Restarting the router (including also a factory reset)
- Private DNS - toggle off
- Connection settings to default

Thanks for your help!
